Had an induction on photography an how to use the equipment, that we can rent from the ERC with Dave. There is a wide variety of technology available to rent. We got given a Canon DSLR.
The Canon was a digital camera. We learnt the general basics, of how to work it. We went into the functions of the lens, how to change the lens, the quality off the files, different programme modes & how to change those, Exposure, ISO, shutter & white balance. Will explain about each section below.
The lens on the Canon, was a zoom lens with a variable focal length lens, it can be more adaptable. Ranges from 18mm – 55mm , referring to the focal length of the lens. The lens was set on 35mm which is standard. A wide angle would be smaller, a telephoto lens bigger. If the number is bigger than 35mm the image will start narrowing.
Auto focus & manual focus. But will let the camera focus the image for you, as manual you will have to adjust the lens to focus. Stabiliser helps the movement within a shoot appear smoother.
When changing the lens , best to make sure you have the other lens at hand to change. You want to tae your time , be careful but you don’t want to allow any dust to get into the camera itself, as could effect the image quality. You click down the button on the right hand side of the lens, pop it out, the new lens will line up with two white dots, turn to connect.
Not all lens will attach in the same way, some you will have to turn in the opposite direction for them to connect properly. Either left or right.
The menu had six options varying in colour. The blue is playback settings, red image quality and yellow system settings.
When formatting the card, check that no one has locked the card, with the yellow switch on the side. It probably means they have images on there they don’t want you to delete. Its a handy way of being able to protect your images, but its not a hundred percent secure, always make sure you have backed up your images after shooting.
Have a range of image quality & sizes. Ranges from small, medium & large files. The rounded and stair looking shapes are jpegs. JPEGS compress the image, where as with the RAW files it holds the most amount of information it can regarding the file. Then again a RAW file isn’t always readable on all programmes you may have to download a programme to change the file.But generally would choose RAW over JPEG.
Here we have various options. They all change the camera settings to get different styles of images.
Starting from the A.
- Auto – Everything set up for you.
- No Flash – Flash is Disabled , use in places where flash isn’t permitted.
- Creative Auto – Offers control over flash & background blur. Limited control over exposure.
- Portait – Produces softly focused background
- Landscape – Both near an distance features in focus, boost the colour & contrast. Flash is also disabled.
- Close up (Makro) – Produces softly focused backgrounds, good for close ups & nature.
- Sports – Faster shutter speed selected, capture without blur.
- Night Portrait – Flash with a slow shutter speed, brighter background to help dim lighting.
- Video – Digital movies.
- A-dep – Selects the F.Stops needed to frame the objects, sharp focus, also selects shutter speeds. Full control , over most settings.
- Manual – Full control of everything.
- Aperture Priority – Selects shutter speeds, colour & flash control.
- Shutter Priority – Selects the F.Stops, Colour & flash control.
Created using three variables, shutter speed , aperture & ISO.
Shutter speed is listed as fractions of a second, in speech marks. Can help stop blur & movement. Short exposure will stop the movement within image, long exposure will prolong the movement captured within the image. Two images below show short an long exposure.
The F.Stops. Its how big the hole is that lets the light through. Bigger the hole the more light, smaller the less light. Controls the depth of field also, so how an object looks in relation to its surroundings, can be changed by depth of field.
Sensitivity to light. Bigger the ISO the more sensitive to light, the smaller the ISO the less sensitive., ranges from 100/3200 an higher. Larger the number the more noise that is created in the image, giving it quite a grainy effect. But you can compensate that using the other two settings.
Was great fun learning the basics of a digital SLR. Being shown what effects what in an image, an how to change it.
